Coronary stent implantation in acute vessel closure 48 hours after an unsatisfactory coronary angioplasty

1990

We report the implantation of a balloon-expandable stent in a patient with acute vessel closure in the state of evolving myocardial infarction following 48 hr after unsatisfactory coronary angioplasty. The stent was implanted after successful recanalization of an occluded left anterior descending artery, with repeated unsatisfactory results of balloon angioplasty. Adjunct thrombolytic therapy was contraindicated. No residual stenosis was documented in immediate control angiograms, or after 24 hr, 3 weeks, and 4 months.

Behaviour influences cholesterol plasma levels in a pig model

2012

Little is known about the relationship between feed intake behaviour and cholesterol levels in humans. This can be attributed to the fact that feed intake behaviour in humans is difficult to assess. The relationships between feed intake, feed efficiency and feed intake behaviour, and cholesterol and triglyceride levels were investigated at an average age of 187 days, in a pig model consisting of 202 Duroc barrows. Feed intake and feed intake behaviour were recorded individually and daily by means of an electronic identification system. Animals with high levels of total cholesterol also had high levels of high-density lipoprotein (HDL), low-density lipoprotein (LDL) cholesterol and triglycer…

Factors Correlating with Restenosis after PTCA

1991

Since its introduction in 1977 [7, 8], PTCA has been widely used in patients with coronary artery disease. Restenosis with recurrence of angina remains the major problem, limiting the long-term success after PTCA. Reported restenosis rates vary from 17% to 47% [9–19, 22–26]. In larger series [12, 15, 26] a restenosis rate of about 30% was constantly found, irrespective of the definition of restenosis in use.

Coronary Angioplasty in Unstable Angina

1990

When Gruntzig introduced the revolutionary method of percutaneous transluminal coronary angioplasty (PTCA) for the treatment of coronary artery stenoses, he initially devoted this technique only to patients with stable angina pectoris [8]. Very soon, however, it was discovered simultaneously by Williams et al. [19] and by our group [12] that this method can also be used in patients with unstable angina pectoris. The earliest experiences with PTCA in 1980 were published by our two groups (Table 1). In these series the average degree of stenosis was somewhat lower than that today, while the residual stenosis after treatment was slightly higher. The very rough balloons and guiding catheters av…

Residual vein thrombosis and D-dimer for optimizing duration of anticoagulation in idiopathic deep vein thrombosis.

2010

Long-term anticoagulant treatment is highly effective in preventing recurrent Venous Thrombo-Embolism (VTE) in patients with idiopathic Deep Vein Thrombosis (DVT) of the lower limbs, though associated with an increased risk for major bleeding that may offset the benefits of anticoagulation. Accordingly to recent guidelines, patients with idiopathic DVT should be treated for at least 3 months and then should be evaluated for the risk-benefit ratio of long-term therapy. However, such ‘time for decision’ is often unclear and the optimal duration of VKA remains debatable. In recent studies, markers for the assessment of the individual risk for recurrent thrombosis have been proposed, which can …

Effects of PEEP on Residual Vascularization in Oesophageal Substitution Gastroplasty by Surface Oximetry-Capnometry and Photoplethysmography

2003

<i>Objective:</i> To evaluate the effects of positive end-expiratory pressure (PEEP) on residual vascularization in gastric tubes for oesophageal replacement. <i>Design:</i> Experimental open study. <i>Materials:</i> Eleven mongrel dogs. <i>Methods:</i> Intestinal parietal blood flow was evaluated by photoplethysmography (PPG) and measurement of surface oxygen (PsO<sub>2</sub>) and carbon dioxide (PsCO<sub>2</sub>) tensions under basal conditions. After Akiyama’s tubular gastroplasty, three levels of PEEP were administered. At each level, fluids were infused to counter the drop in cardiac output. PPG, surface gas tensio…

Heavy and Light Chain Monitoring in High Risk Smoldering Multiple Myeloma Patients Included in the GEM-CESAR Trial: Comparison with Conventional and …

2019

Introduction: The GEM-CESAR trial is a potentially curative strategy for high-risk smoldering multiple myeloma (HRsMM) patients (pts) in which the primary endpoint is the achievement of bone marrow minimal residual disease (MRD) negativity. However, other methods of disease evaluation in serum such as heavy+light chain (HLC) assessment, with a potential complementary value to the IMWG response criteria, have also been tested. Aim: To evaluate the performance of HLC assay in HRsMM pts at diagnosis and after consolidation, comparing the results with standard serological methods and Next Generation Flow (NGF) for the assessment of bone marrow MRD. Patients and Methods: Ninety HRsMM pts include…

Clofarabine Significantly Increases Eradication of Minimal Residual Disease of B-Precursor ALL Compared to High-Dose Cytarabine in Randomized Trial C…

2020

Background Since the FDA approval of clofarabine for the treatment of relapsed or refractory acute lymphoblastic leukemia (ALL) at childhood, several studies have been launched which put clofarabine under scrutiny in combination with other cytostatic drugs as second or third line therapy. As a novel treatment-strategy we introduced the combination of clofarabine with pegylated asparaginase (PEG-ASP) in a randomized fashion in comparison to the standard consolidation course with high dose cytarabine (Hidac) combined with PEG-ASP into the frontline management of ALL within the CoALL 08-09 protocol. The primary objective of the study was to compare the MRD based assessment of the cytotoxic eff…

Modelació de sedimentadors en plantes de tractament d’aigües residuals. Aplicació al procés de fermentació – elutriació de fangs primaris

2005

La depuració de les aigües residuals requereix la consumació de molts processos de transformació de forma simultània i/o consecutiva, que fan molt difícil el seu estudi. A més, la complexitat dels processos de depuració va en augment no sols per l'aparició de requisits d’abocament cada vegada més exigents, sinó també per les noves tendències cap al desenvolupament sostenible aplicades a aquest procés i centrades fonamentalment en l’estalvi energètic i la recuperació de nutrients de les aigües residuals per millorar el seu cicle de vida. Per aquest motiu, es fa necessari l'ús d'eines de simulació que tinguen en compte tots aquests processos mitjançant un model matemàtic adequat i ajuden a de…
